Brass Water Solenoid Valve 2W Series

2W water solenoid valveIt is an industrial equipment controlled by electromagnetism, which is an automation basic element used to control fluid, with diversified functional structure, widely used in industry and manufacturing, this modelsolenoidsCapable of electrically controlling the on-off of fluid lines.

常闭型和常开型的区别

General daily use of solenoid valves are divided into two major types of normally closed and normally open, normally closed solenoid valve means that the coil is not energized when the gas path is broken. Normally open type solenoid valve means that the coil is not energized when the gas path is open. Normally closed solenoid valve action principle: energize the coil, the gas path is connected, once the coil is de-energized, the gas path will be disconnected, which is equivalent to the point of action. Normally open type solenoid valve action principle: energize the coil, the gas path is open, once the coil is de-energized, the gas path will be open, which is also point action.

按不同工作需求如何选择

• 当电磁阀需要长时间关闭，并且关闭的时间多于开启的时间应选用常闭型。

• 当电磁阀需要长时间开启，并且开启的时间多于关闭的时间应选用常开型。

• 需要长时间开启的同时又要长时间关闭时，要选自保持式电磁阀，也叫常开常闭型电磁阀。

• 但是有些用于安全保护的工况，如炉、窑火焰检测，则不能选常开的，应选可长期通电型。

安装说明

• 电磁阀管径保持横向水平安装，线圈保持竖直安装。

• 出水管路带逆流需加装check valveThe

• 介质必须清洁无腐蚀（可通水、压缩空气）。
